用于RFID系统数据处理的排序邻居算法性能分析

PERFORMANCE ANALYSIS OF USING SNM ALGORITHM IN RFID SYSTEM DATA PROCESSING

结合RFID系统数据的数据结构,采用控制变量的方法,评估使用SNM(sorted neighborhood method)算法对RFID数据处理的性能影响因素,包括窗口大小以及SNM原始数据的重复数量。实验证明,使用SNM处理RFID读取到的数据的关键因素是重复数据所占比例和处理窗口的大小。实验也验证了使用随机窗口大小对优化处理性能没有影响。

Series of experiments, combining the data structure of RFID system and using the control variate method, are designed to evalu- ate the performance factors of the RFID data sequence using SNM, which includes the dealing window size and the repeat number of the origi- nal RFID data sequence. By analyzing the results of the experiments, the conclusion is that the most important factor is the scale of the repeat number in RFID data sequence and the dealing window size. Besides, the result proves that using random window size fails to achieve better performance.
